请教：商务信函中“护照正在办理”怎么表述比较好啊？

Application for the passport is being processed.

passport is in process. 有表达问题， 是中文式的英文, 那是护照在进行中， 进行甚么 ？
passport 是要申请 application (apply) 的

Passports are currently being processed 那更含糊 － process passports ? process 些甚么 ？ process 申请， 还是 process 归类 ? 修补 ？加工 ？处理 ？

Your passport is in process.

翻译的好

Passports are currently being processed
